      document.write("date 1 is :- " + d1); 
      document.write("<br>"); 
      document.write("date 2 is :- " + d2); 
      document.write("<br>"); 
      if (d1.getTime() === d2.getTime()) 
          document.write("Both  are equal"); 
      else
          document.write("Not equal"); 

Ex:-

      var d1 = new Date( " Wed Nov 26 2019 09:52:06 " ); 
      var d2 = new Date(); 
      document.write("date 1 is :- " + d1); 
      document.write("<br>"); 
      document.write("date 2 is :- " + d2); 
      document.write("<br>"); 
      if (d1.getTime() === d2.getTime()) 
          document.write("Both  are equal"); 
      else
          document.write("Not equal"); 

Result of above code is:
